Title: Semiconductor memory device
Inventor: HARADA MOEMI
IPC: G11C11/401
Filed: 1991-06-27
Abstract: PURPOSE:To enable a reset data to be written into a memory cell stably by allowing a dummy word signal generation circuit to deactivating a circuit for compensating a reference level at the time of flush write(FW). CONSTITUTION:When a semiconductor memory device is set to an FW mode, a dummy word signal generation circuit 100 performs control to suppress generation of a dummy word signal with the FW mode flag signal which is generated only at the FW mode or a signal which is obtained by performing a logic operation with the FW mode flag signal. In this manner, the FW mode flag signal prevents the dummy word signal from being generated by the FW mode flag signal in the case of the FW mode (deactivation of circuit for compensating a reference level), thus enabling a potential difference between digit lines which is generated by a previous restorage cell data of a memory cell and that between worst digit lines to be improved.

Abstract: PURPOSE:To correct a focus dislocation generated in an optical system, by bringing a signal recorded in a test track to test reproduction by varying a focal position synchronously with a rotation, and detecting a focal position where the amplitude of a reproducing signal becomes maximum. CONSTITUTION:A test track is provided on the recording area of the inner peripheral part of a recording medium, and in a regular focus control position, a test signal is recorded. Before reproducing a data, a sweeping signal S11 varied successively in accordance with a sector address S10 is generated by a sweeping data generating circuit 25, and reproduced in a different focus control position at every sector, through a D/A converting circuit DAC 21. This reproducing signal S3 becomes a signal whose amplitude is different at every sector, therefore, it is brought to an envelope detection by a detecting circuit 27, and a sector whose amplitude is maximum is detected through a detecting circuit 26. Subsequently, it is corrected to a focus control position at the time when the sector whose amplitude is maximum has been recorded. When the correction is ended, a light spot is moved to a data recording area and reproduction is executed. In such a way, the focus dislocation is decreased.

IPC: G11B7/135
Filed: 1987-07-23
Abstract: PURPOSE:To prevent quantity-of-light reduction by luminous flux branching and to improve the carrier wave versus noise ratios (C/N) of a regenerative signal by selectively switching optical paths in accordance with the contents of a reflected light from an optical disk. CONSTITUTION:Laser light from a laser diode 1 passes through a collimator lens 2 and radiates an optical disk 6 through a beam splitter 4. Reflected light is reflected at the beam splitter 4 and is made incident on a polarized beam splitter 30 through an electro-optical element 20. At this time, when the data signal part of a recording track is scanned, a switch 21 is turned off, the light to transmit the element 20 is made to transmit the splitter 30 and light-received by a photodetector 8. On the other hand, when a servo signal part is scanned, the switch 21 is turned on and the plane of polarization of the laser light is turned to 90 deg.. Thus, the splitter 30 reflects the laser light in a right-angle direction and light-receiving is executed by a photodetector 12. Consequently, the luminous flux does not branch and the C/N is improved.

IPC: G11B15/087
Filed: 1985-08-23
Abstract: PURPOSE:To easily perform a program searching by making it possible to record an index signal also in case of recording from a recording pause at the recording of only voice. CONSTITUTION:A sound signal and a video signal are recorded from external signal input terminals 3a, 3b in a magnetic tape through a sound signal recording circuit 5 and a video signal recording circuit 6. Only when a synchronizing signal is included in the video signal, a video signal detecting circuit 10 outputs a logic low level output 10a. Since the output 10a is in the low level when the recording signal is the video signal including the synchronizing signal in said constitution, an index signal recording circuit 13 is not driven even if a high level signal is outputted from a system control circuit 15 at the release of the recording pause. Since the output 10a is in the high level at the recording of only the sound signal, an index signal is recorded by a signal 15a also at the release of the recording pause. In case of recording from a stop mode, an output 15b is used to actuate the circuit 13.
